Nitric acid is a corrosive chemical used in the manufacture of dyes, explosives, and fertilizers.
“Exposure to nitric acid can cause irritation to the eyes, skin and mucous membranes; it can also cause delayed pulmonary edema, pneumonitis, bronchitis, and dental erosion,” according to the National Institute for Occupational Safety and Health. “Nitric acid is very aggressive. Workers can be harmed by exposure to nitric acid.”
The tanker involved in the collision was carrying liquid nitric acid.
Interstate 10 remains closed in both directions between Rita and Kolb roads in Tucson. Please continue to avoid this area.

In addition to closing affected sections of the highway, Arizona officials ordered everyone within a one-mile radius of the spill to take cover in place.
“Reminder: This will be an extensive closure. Motorists in the Tucson area should expect an impact on their ride Wednesday morning,” the Arizona Department of Public Safety said in a statement.
“Joint Command evacuated an area half a mile around the scene. Joint Command has ordered shelter in place within one mile around the scene,” the agency added.
The Arizona trucker spill comes more than a week after a train near East Palestine, Ohio derailed, prompting officials to conduct a “controlled release” of five derailed train cars containing vinyl chloride to prevent a “catastrophic explosion”.
